With the development of the digital industry, fast file uploading is crucial for improving work efficiency. The traditional method of users directly uploading to the source station cannot meet the demand for high-speed uploads. CDN edge nodes are widely distributed in major cities, mainly occupying downstream bandwidth to accelerate internet applications, and they have a significant characteristic of having a large amount of unused upstream bandwidth.Based on the distributed nodes of CDN and the massive redundant upstream bandwidth, this paper proposes an upload acceleration scheme based on CDN relay. It upgrades the CDN scheduling center to enable users to access CDN edge nodes nearby, and designs a back-to-source path selection algorithm that comprehensively considers delay, jitter, and packet loss (Integrated Delay-aware Minimum Path Algorithm, IDMP) to implement CDN node uploads to the source station.The experimental results show that this scheme improves the upload speed by 659%, which can better support the acceleration of cloud disk uploads and the implementation of file gigabit instant transmission services.
